IMPRovEMENT In STQNE-cRusl-IERS.

Specification forming part of Letters Patent No. 166,504, dated August10, 1875; .application tiled June 26, 1875.

To all whom it may concern:

Be it known that I, JOSHUA GoMLY, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and ImprovedStone-Crusher, of which the following is a specification:

My invention relates to stone-crushers having one stationary and onevibrating jaw; and it consists of a toggle-bar contrivanee incombination with the crank-shaft and the rod connecting it with themovable bar in a manner calculated to apply very great force with acomparatively light and simple construction7 which is at the same timesimple and durable, and aii'ords a very easy motion; and in combinationtherewith is a contrivance for givingV vertical or endwise motion to themovable jaw,

to be used or'not, as may be found desirable, the said motion beingpreferable in some cases.

Figure 1 is a longitudinal sectional elevation of my improvedstone-Crusher, taken on the line a: w of Fig. 2. Fig. 2 is a plan View,and Fig. 3 is a transverse section taken on line y y of Fig. 2.

Similar letters of reference indicate correspondin g parts.

connecting-rods by which the movable jaw is coupled to the rocker-head Fof the togglebar Gr, which is pivoted to the frame at H, and

the rocker is connected to the crank shaft I by the coupling-rods K. Bythe swinging of the rocker F around its pivot H, powerful vibratingmotion is imparted to the lower end of the vibrating jaw BI by means ofcomparatively light and inexpensive connections, and by working the jawthrough the medium of the rocker F and toggle-bar G a very considerableleverage is obtained. L represents links or couplings, by which thevibrating end of the movable-jaw is connected to the trunnions of thestationary jaw, to make the jaw rise and fall a little at the same timethat it vibrates, the pivot-bearing of the jaw being contrived to permitsuch motion.

Having thus described my invention, I

claim as new and 'desire to secure by Letters Patentl. The combinationof therocker F and toggle-bar G with the crank-shaft and movable jaw,and the connecting-bars L, substantially as specified.

2. The vibrating end of the movable jaw, coupled to the stationary jawby the rod L,

vand pivoted in bearings allowing it to have lengthwise motion, incombination with the rocker F and connecting-rod E, substantially asspecified.

3. The vibrating jaw, having lengthwise motion, and being coupled to thetrunnions of the stationary jaw, substantially as specified.

JOSHUA COMLY.
